Explain this one

A missing moon rock surfaced this week among Bill Clinton’s stuff at an Arkansas library.

That may be one of the oddest sentences you’ll read this year. It’s true, however. (Read about it here.) A worker found it while going through boxes, trying to catalog items from Clinton’s time as governor.
Critics of the former president liked to stereotype him as an unsophisticated Southern hillbilly. I suppose this fits into that stereotype. But, really, who knows how it got there?
The rock was from Apollo 17, which brought back 50 samples, one for each state. That was long before Clinton was governor, however.
This raises a larger question. Does the nation really know the location of the 843 pounds of moon rocks astronauts brought home during the late ’60s and early ’70s? Until we muster the money and the will to go back there, those things will be kind of rare.
